Real-Time Aurora Activity

Discover the likelihood of witnessing the Northern or Southern Lights from your location.

The aurora borealis (Northern Lights) and aurora australis (Southern Lights) are beautiful natural phenomena caused by solar particles colliding with Earth's atmosphere. This page provides the current probability of auroral activity based on real-time space weather data.

Solar Wind Conditions

Solar Wind Speed: 602.3 km/s

Solar Wind Density: 6.94 protons/cm³

Bz Component (IMF Z-axis): -3.20 nT (Southward)

Last Update: 2025-06-25 18:32

The Bz component measures the north-south orientation of the Interplanetary Magnetic Field (IMF), a key part of the solar wind’s magnetic field. Its value is given in nanoteslas (nT).
- When Bz is negative (e.g., -6.3 nT), the IMF points southward. This southward orientation allows solar wind energy to more effectively enter Earth’s magnetic field, often leading to stronger auroral activity.
- When Bz is positive (e.g., +4.2 nT), the IMF points northward. A northward orientation typically suppresses the energy transfer, reducing the chance of visible auroras.
Example: If the Bz component is -6.3 nT, the IMF is southward, creating favorable conditions for auroras.

Global KP Index Forecast (Tue, 17 June 2025 – Fri, 27 June 2025)

The Kp index measures geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm). This chart presents both recent observations and forecasted Kp values from 17 June, 20:00 through 27 June, 20:00, helping you monitor geomagnetic trends and anticipate periods of increased auroral activity.

Bz (IMF Component)

The Bz component of the Interplanetary Magnetic Field (IMF) indicates the north-south orientation of the magnetic field carried by the solar wind. Negative Bz values can connect with Earth's magnetic field, potentially triggering geomagnetic storms. Monitoring Bz helps predict space weather impacts on Earth.
